Hi, Grantst ... I so sorry that your husband (and you) are going through this, but glad you found us. You will find a lot of support here, especially from the other caregivers on this forum.
The most worrisome thing to me is your husband's weight loss. It sounds like your husband is in denial (I was, too, at first, so I sympathize), but it is essential that he try to gain some of that weight back. My neuro told me that gaining back lost weight works even better than Rilutek at slowing down progression and extending life. (Rilutek is the only med approved for ALS.)
If he enjoys his meals, that's great! But he's clearly not eating enough to maintain his weight, probably because eating is so slow and difficult. So he needs some boost to regain his lost weight.
I make milkshakes with Ensure, protein powder and ice cream that have between 700-1,000 calories each. I had lost 24 pounds, and have gained back 10 in a few months. The milkshakes are really good. Maybe he would agree to drink something like that in the evening.
This is one place where PALS (Patients with ALS) have control over this disease. The eating tube may be something he will need very soon, especially if he's unable to take in enough to keep his weight up. But do try to convince him right away to eat supplements. And, as you prepare his meals, give him the highest-calorie foods you can think of. It is really important for him not to loose more.
Good luck,
BethU
